II. SYSTEMATIC. 



This is rather a small tree, attaining sometimes, however, a height of 50 or 

 60 feet in favourable situations, such as water courses; it has a hard, compact, 

 furrowed bark. The branches and branchlets slender and angular, owing to the 

 shape of the decurrent green leaves, the internodes short, the free portion of 

 leaf perhaps a little more acute than C. gracilis, which has similar angular 

 internodes. Male amenta, mostly solitary, terminal, and small. Female amenta 

 in panicles at the base of the branchlets. 



Fruit cones not densely clustered on scarcely thickened branches, mostly 

 solitary-, under J inch in diameter, globular ; \-alves six, alternately smaller, the 

 larger ones dilated upwards into a wedge-shaped apex, the sporophyll producing 

 a pronounced dorsal spur, at first smooth but becoming rugose with age, the 

 smaller valves about half the width of the others, and tapering upwards, but 

 otherwise similar, distinctly channelled at the edges. Seeds two-winged. 



The tree is easily determined in the field by its fastigiate growth, and in 

 herbarium material by its characteristic slender branchlets, and fruits, the larger 

 valves of which have a broadly rhomboidal apex, a feature that distinguishes 

 the species from all others, except C. Tasmanica. 



III. LE.WES. 



(a) Economic {vide Chemistry). 

 {h) Anatomy. 



.•\ cross section through the three decurrent leaves gives an outline fairly 

 distinct from a corresponding section of any other species of Callitris, as 

 shown in the several plates. 



Th'- \,uic)u> Us.bues or organs of the leaves are found to occupy a relatively 

 similar position to those described more fully under such species as C. glauca, 

 C. calcarala, and C. robiista, and so arc not so fully particularised here, as the 

 illustrations define their situations .
